I made an lmd_door and each time you use it I want it to make a sound (sound/movers/doors/door_huge_start.mp3). So I tried using the target key on the door, didn't work, and tried using a target_relay that targets both the door and the sound, it worked, but the sound kept playing over and over again. What's wrong? It'd be easier if lmd_door had a soundset key.. ¬¬

Put spawnflags 0 to the target_speaker and it works. Only those around can hear the snd, it starts off and doesn't loop. For my rentable house, the rentable terminal (a button) targets house_door. So it targets both the door and the target_speaker (both have targetname house_door). No need of target_relay in that case.

EDIT: Actually now I have the button targets house_door, and the door targets the sound. This way people won't spam the sound by constantly pressing the button because the sound only plays when the door opens and not when you click the button.
